: Used to simulate the growth, propagation, and decay of wind-generated waves and offshore swells.
"Come on, Mike," Elias whispered to the software. "Talk to me."
DHI offers a full range of linked modules, allowing a single software ecosystem to handle hydrodynamics, sediment, water quality, and waves. dhi mike 21
MIKE 21 simulations are computationally intensive, especially when running Flexible Mesh models with fine resolutions. DHI has optimized the software to utilize modern computing architectures:
At its heart, MIKE 21 is a two-dimensional, hydrodynamic modeling engine. Unlike simpler one-dimensional models that simulate flow only along a river channel, a 2D model solves the depth-averaged Navier-Stokes equations (specifically the Saint-Venant equations for shallow water). This means it simulates how water moves both horizontally across a landscape and through time, accounting for variations in depth, velocity, and direction. The software’s flexible mesh technology—most notably its use of a non-structured, cell-centered finite volume method—allows it to represent complex, irregular coastlines, islands, and man-made structures with far greater precision than traditional rectangular grids. This adaptive mesh refines resolution in areas of interest (e.g., around a bridge pier or a narrow inlet) while maintaining coarser resolution in deeper, less critical zones, balancing accuracy with computational efficiency. : Used to simulate the growth, propagation, and
The Flexible Mesh approach eliminates this bottleneck by allowing users to construct computational domains using unstructured meshes consisting of variable-sized triangles and quadrilaterals.
The digital wind hit. The color map shifted. The deep blue of the harbor turned a violent purple as the storm surge pushed through the entrance. The vectors—little black arrows representing velocity—began to dance and twist. This means it simulates how water moves both
